* [https://launchpad.net/nevow Divmod Nevow] is a templating toolkit that provides its own resource model and simple application server API. It requires Twisted, is fully integrated with the Twisted reactor, provides mechanisms for asynchronous page rendering, and an event-driven [http://en.wikipedia.org/wiki/COMET_(programming) COMET]/AJAX implementation called [http://divmod.readthedocs.org/en/latest/products/nevow/athena/index.html "Nevow Athena"]. Nevow uses Twisted Web, but provides its own request objects and resource model on top of it.

* [https://launchpad.net/mantissa Divmod Mantissa] is a full-featured multi-protocol application server, with a built-in object database, authentication model based on Twisted Cred, a capability-based security model, and many more features. It integrates Nevow (and therefore Twisted Web) and a number of other Twisted-related technologies to provide a full-featured system.

The short version is that this is more complicated in Twisted than in other tools at the moment. Sadly, you aren't going to find a straight-up competitor with the sort of polished web presence and easy instant integration with your SQL database and existing environment that the aforementioned products offer.
